I think generally people are only sensitive to people who are not mutually respectful.

A lot of "sensitive" people are not very respectful of others. From my observation it's often a very asymmetric relationship.

I find sugar coating to be highly insulting. In my experience, such people are more often secretly disrespectful and less careful with the truth.

Note that I said nothing about sugar coating. Those were words you chose.

Edit: Interesting. I initially wrote, "Please note..." but then decided to be blunt and leave off the Please. I guess I was, um, too blunt.

Interesting. I made no accusation against you. Is your comment, in fact, completely straightforward?
